LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Prunus persica L. Batsch.

VARIETY DENOMINATION

‘FLATBELLA’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of flat white peach tree, Prunus persica L. Batsch, which has been given the variety denomination ‘FLATBELLA’. This new tree produces fruit with a long shelf life without alteration both on the tree after growth completion and after harvesting, large fruit with very good eating quality, flesh fruit for fresh market in early July in the Pyrénées-Orientales department, France. Contrast is made to ‘FLATPRETTY’ (Plant patent application Ser. No. 11/434,796) flat white peach tree, standard variety, for reliable description. ‘FLATBELLA’ is a promising candidate for commercial success in that it has a semi-late period flowering, flat fruit with very long shelf life without alteration after harvesting, and so a very durable fruit.

ORIGIN OF THE VARIETY

‘FLATBELLA’ flat peach tree originated in a cultivated area of the south of France, in the Pyrénées-Orientales department, where it was tested. The male parent is ‘FLATPRETTY’ (Plant patent application Ser. No. 11/434,796) flat white peach tree, very productive, with a very attractive fruit of pink red blush color on a pink cream ground color. The female parent ‘NECTARMAGIE’ (U.S. Plant Pat. No. 17,579) is a white nectarine tree, very productive, with very attractive and very large fruit. ‘FLATPRETTY’ (Plant patent application Ser. No. 11/434,796) variety was obtained by open-pollination of ‘MAILLARFLAT’ (SweetCap®, non-patented). It blooms in March in the South of France. More particularly, it blooms 2 days before ‘MAILLARFLAT’ (SweetCap®, non-patented), between the 9^(th) and the 15^(th) of March, and 3 days time long more. The first fruit of ‘FLATPRETTY’ ripens at the end of June and beginning of July, 30 days before ‘MAILLARFLAT’ (SweetCap®, non-patented). More particularly, it approximately ripens between June 28^(th) and July 9^(th) ‘NECTARMAGIE’ (U.S. Plant Pat. No. 17,579) results from an open pollinated cross of ‘MAILLARMAGIE’ (Magique®) white nectarine tree that was used as the seed parent. As ‘MAILLARMAGIE’ (Magique®) nectarine tree has non-showy (campanulate) flowers, flowers blooming occur before pollen maturity. Cross-pollination with varieties in the vicinity of the mother-tree should have occurred. Pollen parent is unknown. It blooms in early March in South of France, more particularly one day after ‘MAILLARMAGIE’ (Magique®) variety, between March 3^(rd) and March 15^(th). The first fruit of ‘NECTARMAGIE’ (U.S. Plant Pat. No. 17,579) nectarine tree ripens in July, more particularly about 3 to 4 days before the first fruit of ‘MAILLARMAGIE’ (Magique®) variety, between July 3^(rd) and July 13^(th). It was obtained by hybridizing and propagated by grafting. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of this standard rootstock on this scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually in Elne, Pyrénées-Orientales department, France.

SUMMARY OF THE VARIETY

The new and distinct variety of flat white peach tree ‘FLATBELLA’ blooms in late February near Elne in the Pyrénées-Orientales department, France. The flowering period is considered as semi-late in the South of France. More particularly it blooms between the 24^(th) of February and the 3^(rd) of March. The first fruit of ‘FLATBELLA’ ripens in early July, 7 days earlier than ‘FLATPRETTY’ (Plant patent application Ser. No. 11/434,796) variety. More particularly it ripens between the 8^(th) of July and the 17^(th) of July.

DETAILED BOTANICAL DESCRIPTION

The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruit by ‘FLATBELLA’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are vigorous and large stature half-standing in a semi-spread to semi-upright aspect. The flowering shoot is present excluding brushwood side away from sun. Flowering begins semi-early in springtime. The type of flower is showy, with medium petal size. Petals are medium pink. Leaf glands are present and reniform. Time of maturity for consumption is considered semi-early. The fruit flesh is white with a red pigmentation under the skin and in the stone cavity. Fruit skin is very thick, of bright red color on an orange red ground. The stone is of small to medium size and the flesh is semi-adherent to adherent. Fruit taste is semi-sweet.

Compared to ‘FLATPRETTY’ (Plant patent application Ser. No. 11/434,796) the maturity period is earlier of 7 days. The blooming time is considered semi-late and occurs 2 to 3 days earlier. The fruit is of a superior quality as far as presentation is concerned. The fruit is of a homogenous bright red blush color. The pistil end is well closed.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white flat peach tree, the following has been observed during the third fruiting season under the ecological conditions prevailing at the orchards located near the town of Elne, in the Pyrénées-Orientales department, France. All observations have been made on rootstock cultivar. The rootstock was a ‘Franc Inra Montclar®’ tree. All major color code designations are by reference to The R.H.S. Color Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree:     -   -   Size.—Medium to high as compared to other common commercial             peach cultivars. The tree size the first year was             approximately 2.50 meters. The tree was pruned during each             following dormant season to a height of approximately 2.50             meters. Current seasons shoots growth could reach 0.80             meters. So the tree size from the second year (second and             next years) reached a final height of 3.30 meters with             current seasons shots length comprised.         -   Spread.—Approximately 1.0 meter. The whole orchard was             oriented to a central leader organization, with tree lines             spaced of 4.0 meters and trees spaced of 1.0 meter in a same             tree line.         -   Vigor.—Very vigorous. The present variety grew from about             60.0 centimeters to 80.0 centimeters in height during the             first and following growing seasons. For second and             following seasons, the variety was pruned to an approximate             height of 2.50 meters.         -   Productivity.—Very productive. Fruit set is spaced by             thinning to develop the remaining fruit into the desired             market sized fruit. The number of the fruit set varies with             the prevailing climatic conditions and cultivar practices             employed during the bloom period, and is therefore not             distinctive of the present variety.         -   Bearer.—Considered regular. A thinning of 1 fruits on 2 was             necessary for the tree valorization. Thinning may not be too             important because of the high magnifying potential of the             fruit.         -   Form.—Semi-spread to semi-upright naturally.         -   Density.—Considered medium dense to dense.         -   Hardiness.—The present tree was grown and evaluated in             France. The variety appears to be hardy under typical             central Pyrénées-Orientales department climatic conditions.             Fruits remain very attractive because they are well colored             with an excellent semi-sweet flavor. Experimentations on             different sites with winter chilling requirement comprised             between 350 hours and 1200 hours showed a good behavior of             the tree in all cases. No damages were caused by ascertained             temperatures as low as −12° degrees Celsius. The tree was             also resistant to frosty springtime weather. In a general             manner, the flat fruit varieties are more sensitive to             critical low temperatures and to climatic variations. This             is due to the ovule that is less protected than in the             classical round fruits. The implantation is recommended             where the peach tree is able to grow and more particularly             in the ones that have the less frosts. -   Trunk:     -   -   Diameter.—Approximately between 5.5 centimeters and 7.0             centimeters when measured at a distance of approximately             30.0 centimeters above the soil, on trees from the third             growing season.         -   Bark texture.—Rough, with lenticels.         -   Lenticels.—Numerous lenticels are present on trees from the             third growing season. The lenticels range in size from             approximately 0.2 centimeters in height and about 0.3 to 0.5             centimeters in width.         -   Lentical color.—The outside surface of lenticels has a             silver-grey color (RHS GREY 201 C-D), whereas the inside             surface is brown (RHS GREYED ORANGE 166 B).         -   Bark coloration.—The bark has a silver-grey color a little             more pronounced than lenticels outside color (RHS GREY 201 A             to RHS BLACK N 200 B-C). -   Branches:     -   -   Size.—Mature branches and current season shoots are             considered medium to thick for the variety.         -   Diameter.—Average as compared to other peach varieties. The             current season shoots have a diameter from 4.0 to 8.0             millimeters, and branches of trees from the third growing             season have a diameter comprised between 13.0 and 19.0             millimeters.         -   Current season shoots surface texture.—Average, wood that is             several years old has no furrowed appearance.         -   Crotch angles.—Primary branches are considered variable, but             the crotch angles are generally between 60 degrees and 80             degrees from the horizontal axis. This particular             characteristic is not considered distinctive of the variety,             however.         -   Internode length.—Generally 20.0 millimeters to 35.0             millimeters.         -   Color of mature branches.—Brown (RHS GREY BROWN 199 A-B).         -   Color of current season shoots.—The color of new shoot tips             is considered a pale yellow green (RHS YELLOW GREEN 144 A-C)             on lower part of new shoot tips, whereas the upper part is             colored brown-purple to brown-red (RHS GREYED PURPLE GROUP             187 A-B to GREYED RED 182 A) following the position on the             shoot. -   Leaves:     -   -   Size.—Considered medium to large for the species. Leaf             measurements have been taken from vigorous, upright,             current-season growth at approximately mid-shoot. The ratio             leaf length/leaf width is above 3.38.         -   Leaf length.—From 158.0 to 187.0 millimeters with leaf             petiole. Average length of 177.0 millimeters.         -   Leaf width.—From 46.0 to 72.0 millimeters. Average width of             52.0 millimeters.         -   Leaf base shape.—Concave relative to the leaf longitudinal             axis.         -   Leaf form.—Lanceolate.         -   Tip form.—Acuminate. -   Leaf color:     -   -   Upper leaf surface.—Dark green (RHS GREEN 139 A).         -   Lower surface.—A lighter green (RHS GREEN 137 B) than the             upper leaf surface color.         -   Leaf texture.—Smooth.         -   Leaf venation.—Pinnately veined. -   Mid-vein:     -   -   Color.—Light green with a yellow touch (RHS YELLOW GREEN 145             C-D) and evolves with maturity.         -   Leaf margins.—Slightly undulating.         -   Form.—Considered slightly dentate.         -   Uniformity.—Leaves are isolated or grouped by 2 or 3. In             this last case, it is found one leaf of normal size with one             or two smaller leaves (size-reduction of 50% and more). -   Leaf petioles:     -   -   Size.—Considered medium.         -   Length.—About 8.0 to 12.0 millimeters.         -   Diameter.—About 2.0 millimeters.         -   Color.—Light green to yellow on the upper surface (RHS GREEN             137 C-D) and yellow green (RHS YELLOW GREEN 145 B-C) on the             lower surface. -   Leaf glands:     -   -   Size.—Considered medium. Their length is about 1.0             millimeter.         -   Number.—Generally 2 to 4.         -   Type.—Reniform.         -   Color.—On young leaves, leaf glands color is considered pale             yellow green (RHS YELLOW GREEN 145 B). On older leaves, leaf             glands color turn to a dark brown (RHS GREY BROWN 199 A-B). -   Leaf stipules:     -   -   Generally.—No leaf stipules were observed. But as seen in             the characteristic relative to the leaves uniformity, it is             possible to find leaves by groups of 2 or 3, with a             normal-size leaf and smaller ones. -   Flowers: -   Flower buds:     -   -   Generally.—At pre-floral stage of development, the floral             buds are conic in form with a round tip. Their form is             evolving until blooming, with variables dimensions. Just             before blooming, floral buds are approximately 14.0             millimeters wide and approximately 22.0 millimeters long.         -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development, the bottom of             the flowers buds, or calyx formed by sepals, is of             purple-brown color (RHS GREYED PURPLE 183 A-B to GREY BROWN             GROUP 199 A); the corolla formed by petals, is generally of             medium pink color (RHS RED PURPLE 65 B to 69 C). Petals             color shows an evolution until the end of blooming.         -   Hardiness.—The buds are considered hardy under typical             central Pyrénées-Orientales department climatic conditions.             No winter injury was noted during the last several years of             evaluation in the central Pyrénées-Orientales department,             with winter temperatures as low as −10° C. in January. The             current variety has not been intentionally subjected to             drought or heat stress, but the variety showed a very good             resistance in orchard to temperatures up to 42° C. with an             average temperature between 28° C. and 30° C. during 3 weeks             in summer.         -   Date of bloom.—Generally late February. The first bloom was             observed on Feb. 26, 2005. Second to fifth blooms took place             respectively on Feb. 25, 2006, Feb. 24, 2008, Mar. 3, 2009             and Mar. 16, 2010.         -   Blooming time.—Considered semi-late in relative comparison             to other commercial peach cultivars grown in the             Pyrénées-Orientales department, France. The date of full             bloom is observed at the middle of the blooming period. The             date of bloom varies slightly with climatic conditions and             cultural practices.         -   Duration of bloom.—Approximately 8 to 10 days. This             characteristic varies slightly with the prevailing climatic             conditions.         -   Flower type.—The variety is considered to have a showy type             flower.         -   Flower size.—Considered medium. Flower diameter at full             bloom is approximately 35.0 to 44.0 millimeters.         -   Bloom quantity.—Considered abundant, approximately 45             flowers per meter.         -   Flower bud frequency.—Generally 2 flower buds appear per             node, occasionally 1. -   Petal:     -   -   Size.—Considered medium for the species.         -   Length.—Generally about 22.0 millimeters.         -   Width.—Generally about 22.0 millimeters.         -   Petal form.—Round.         -   Petal count.—Nearly always 5.         -   Petal texture.—Smooth and soft.         -   Petal color.—Medium pink (RHS RED PURPLE 65 B-D) when young,             slightly darkening with advancing senescence.         -   Fragrance.—Soft. -   Petal claw:     -   -   Form.—The claw is considered to have a conic form with a             slightly rounded tip.         -   Length.—Approximately 5.0 millimeters.         -   Width.—Approximately 4.0 millimeters.         -   Petal margins.—Slightly undulating. -   Petal apex:     -   -   Generally.—The petal apices are generally complete at the             tip and round. -   Flower pedicel:     -   -   Length.—Considered medium to long and having an average             length of approximately 4.0 millimeters.         -   Diameter.—Average 2.0 millimeters.         -   Color.—Brown to light brown (RHS GREY BROWN N199 C-D). -   Calyx:     -   -   Internal surface texture.—Smooth and glabrous.         -   Color.—The inner surface of the calyx is considered of             washed-green yellow (RHS YELLOW 13 A-B to YELLOW GREEN 150             A-B) color. The outer surface is purple brown (RHS GREYED             PURPLE 183 A-D). -   Sepals:     -   -   Surface texture.—The outer surface has a smooth texture.         -   Size.—Medium.

This             characteristic is highly dependent upon the prevailing             cultural practices, and therefore is not particularly             distinctive of the variety. -   Fruit form:     -   -   Generally.—Round and oblate to slightly cordiform. The fruit             is generally uniform in symmetry, viewed from pistil end.             Low dented.         -   Fruit suture.—Very shallow, extending from the base to the             apex. No apparent callousing or stitching exists along the             suture line. -   Suture:     -   -   Color.—This has generally a color similar to the blush fruit             color, a bright red (RHS RED 46 A-B to RHS RED 39 A-B) on an             orange red ground (RHS YELLOW GROUP 11 B-C). -   Ventral surface:     -   -   Form.—Smooth.         -   Apex.—In slight dip.         -   Base.—Semi-flared. Shallow.         -   Stem cavity.—Average depth of the stem cavity is about 5.0             to 6.0 millimeters. Average width is about 12.0 to 15.0             millimeters. -   Fruit skin:     -   -   Thickness.—Considered very thick and strong, and tenacious             to the flesh depending on stage of maturity.         -   Texture.—Smooth.         -   Taste.—Semi-sweet, sugared, aromatic.         -   Tendency to crack.—None. -   Color:     -   -   Blush color.—This blush color is a homogenous bright red             (RHS RED 46 A-B to RHS RED 39 A-B). The red blush covers 80%             to 100% of the fruit skin surface. The percentage of the             blush on the fruit skin surface can vary, and is generally             dependant upon the prevailing conditions under which the             fruit was grown.         -   Ground color.—The ground color is orange red (RHS YELLOW             GROUP 11 B-C) on 10% to 20% of the fruit. Appearance is             slightly marbled on the clearest part of the fruit. The             percentage of the ground color of the fruit skin surface can             vary, and is generally dependant upon the prevailing             conditions under which the fruit was grown.         -   Fruit stem.—Medium in length, approximately 4.0 to 5.0             millimeters.         -   Diameter.—Approximately 3.0 to 4.0 millimeters.         -   Color.—Pale green (RHS GREEN 145 A-B). -   Flesh:     -   -   Ripens.—Very homogenous, slow, very evenly.         -   Texture.—Very firm, very dense, crunchy, luscious, and juicy             at harvesting maturity stage.         -   Fibers.—Not fibrous.         -   Aroma.—Pronounced.         -   Eating quality.—Considered very good, sweet and aromatic.         -   Flavor.—Considered semi-sweet. The Brix is generally             superior to 13 degrees and acidity is comprised between 6             and 9 meq/100 ml. The flavor is considered juicy and             aromatic.         -   Juice.—Very juicy at complete maturity.         -   Brix.—Superior to 13.0 degrees. This characteristic varies             slightly with the number of fruit per tree; prevailing             cultural practices; and the surrounding climatic conditions.         -   Flesh color.—White flesh (RHS WHITE 155 D) usually with a             slight red pigmentation (RHS RED 53 B-C) under the skin on             the apex side and in the stone cavity. -   Stone:     -   -   Stone cavity.—Medium, with an ovoid form and dimensions             corresponding to the stone's dimensions.         -   Size.—Considered small to medium for the variety. The stone             size varies significantly depending upon the tree vigor,             crop load and prevailing growing conditions.         -   Length.—From 19.0 to 20.0 millimeters.         -   Width.—From 20.0 to 22.0 millimeters.         -   Diameter.—From 12.0 to 13.0 millimeters.         -   Form.—Oblate, semi-round.         -   Base.—Flat to round. -   Apex:     -   -   Shape.—Oblate with a slight ridge. -   Stone surface:     -   -   Surface texture.—The stone is very furrowed on its entire             surface. Furrows are shallow with a dorsal groove and a             triple ventral groove. The shape of the stone can be             compared to a vertebra.         -   Ridges.—The surface texture is generally characterized by             more prominent ridges along the ventral edges and non             prominent at the apical tip. -   Ventral edge:     -   -   Width.—Considered small to medium, and having a dimension of             approximately 2.0 millimeters at mid-suture. -   Dorsal edge:     -   -   Shape.—Grooved.         -   Stone color.—The color of the dry stone is orange brown (RHS             GREYED ORANGE 173 C-D) with some zones of light brown (RHS             GREYED ORANGE 176 B-C).         -   Tendency to split.—Splitting is absent or very low,             depending on climatic conditions between blooming period and             stone hardening. -   Kernel:     -   -   Size.—Small, round and oblate.         -   Length.—About 8.0 millimeters.         -   Width.—About 8.0 millimeters.         -   Thickness.—About 7.0 millimeters.         -   Form.—Considered oblate, round and slightly grooved.         -   Pellicle.—Slightly pubescent.         -   Color.—The kernel skin is orange brown (RHS GREYED ORANGE             N164 A-B to 165 B). The almond is cream-white (RHS WHITE 155             B). The kernel and its embryo are mature at the time of             fruit maturity.         -   Use.—The subject variety ‘FLATBELLA’ is considered to be a             flat white peach tree of the semi-early season of maturity,             and which produces fruits that are considered large, firm,             and attractively colored. Fruits are excellent for uncooked             consumption, crunchy or at full maturity. Due to their flesh             quality, firmness and density, they can also be             commercialized as 4^(th) range product (packed fruit or             fruit in bags for example). And they are also useful for             both local and very long distance shipping.         -   Keeping quality.—Excellent. Fruit stayed a little more than             one week on tree before harvest and then, has stored well             more than 4 weeks after harvest at 2.0 degree Celsius. They             have a slow maturation and a long shelf life both on the             tree after growth completion and after harvesting without             alteration.         -   Shipping quality.—Considered very good. The fruit of the new             flat peach variety showed minimal bruising of the flesh or             skin damage after being subjected to normal harvesting and             packing procedures. Its resistance to handling during             harvest and packing and its long shelf life without             alteration after harvest easily permit 3 weeks-shipping at             2° degree Celsius.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety is low             sensitive to powdery mildew, and low sensitive to             conservation diseases and decay due to its thick and strong             skin. -   Although the new variety of flat peach tree possesses the described     characteristics when grown under the ecological conditions     prevailing near Elne, Pyrénées-Orientales department, France, it     should be understood that variations of the usual magnitude and     characteristics incident to changes in growing conditions,     fertilization, pruning, pest control and horticultural management     are to be expected.
